Youngest age Delhi School of Excellence in Banjara Hills takes? My partner works close by

Our son is 9 months and at home with us for now. My partner works near Banjara Hills, and we're wondering whether a school pre-primary near the office would be simpler later than a separate daycare near home in Serilingampally. Does Delhi School of Excellence take children younger than nursery age, or does it start at nursery?
